â– After a fuse is replaced
â– If there is an overload in a circuit
The fuses are designed to blow, protecting the wiring harness from damage.
WARNING
â– To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage to the vehicle, and possibly a fire or injury.
Never replace a fuse with a wire, even as a temporary fix.
NOTICE
